Pallet Stacking machine

The utility model relates to a physical distribution device capable of automatically stacking or distributing pallets in an automatization physical distribution system. The utility model is composed of a lifting mechanism and a supporting mechanism, wherein the lifting mechanism comprises a chassis (1), a scissor fork (2), a top pallet (3), a lifting speed reducing motor (4), chains (5), chain wheels (6), etc., and the supporting mechanism comprises a supporting frame (7), a supporting speed reducing motor (8), a supporting board (10), a connecting rod (11), an upper and a lower photodetectors (9), (13) and an electric-control cabinet (14). All actions of the utility model are finished by an electromechanical mechanism without a hydraulic or a pneumatic system so that the structure of the original pallet stacking machine is simplified, and the physical distribution device is an automatization device with simple structure.
